This invention provides an apparatus for pickling pipeor other fabricated forms of material and the like and particularly an i apparatus which will thoroughly and ef5- ciently complete the pickling operation in a mlnimum time. 7

lfiipe, for example, has been comparatively diflicu'lt to pickle successfully due to its at tenuated form audits comparatively in accessible inner-surface with the result that such pickling has hitherto been relatively incomplete and unsatisfactory with detrimental results of a serious nature. Other mate- 5 rails and shapespresent similar or analogous difficulties. I

, One of the objects of the present invention is to provide a pickling apparatus for pipes and the like which will thoroughly and quickly completely pickle the same at every avail able portion of its surface.

Another object isto provide an apparatus whereby thematerial is completely pickled by moving it back andforth in the pickling fluid r so that the latterreaches everyportion of I the surface of the same both interior and exterior. V

A further object is to provide an articulated framework having non-rigid conneca'" tions sothat a material supporting tray as- A further object is to provide for the straight line movement of the material in the pickling fluid.

A further object is to enable the material,

when so desired, to be given a curvilinear or v. arcuate movement which has been found to l be extremely efiicient under certain circumstances and conditions Other and further objects will either be understood by those skilled in this particular p) art or will'be pointed out hereinafter.

A preferred embodiment of the invention sociated therewith may be suitably moved in has been illustrated in drawings wherein:

Similar numerals refer to throughout the several views.

Referring first to Figs. 1 to 7, inclusive, the numeral 10 indicates a fragmentary portion of a suitable pit which may be constructed of any suitable material and in the bottom of said pit are the supporting beams '11 upon whichrests a vat 1201 other suitable tank or receptacle which may be composed of'any suitable material resistant to the action of the; pickling fluid adapted to contained therein and which latter may. be of the usual pickling fluids depending upon the cirthe v accompanying taken at right angles to similar parts "cumstances and conditions involvedor to be met, respectively. 1

Suitably suspended in said vat is" the material supporting tray 13 having partition members. 14, if required for supporting a plurality of rows of material in each of which row may be anum-b'er of pipe sections or other articles or'material superposed on each other. This tray 13 is connected, as shown in Figs. 4: and 5, to a supporting framework 15 which may consist of suitable I-beams or the like and the manner of connecting said tray and said I-beams forms no part of the present invention as it is old and well known in this art. Briefly, it consists of a diagonal rod member 16 connected to each corner of the tray by means of a suitable U-bolt construction 17 passing through an eye 18 in the lower end of the rod. The upper end of the rod is formed with a larger eye 19 which is connected to the pin clamp assembly 20 so as to permit of the tray being swung. It can be suitably swung or moved by an appropriate movement of the supporting framework 15 as will hereinafter 'more fully appear.

The ends of the supporting framework 15 are preferably provided with a suitable roller construction 21, as shown in Figs. 6 and 7. This roller construction is adapted to fit comparatively loosely into the upper end of the articulated upright 22, a socket 23 at the upper end thereof being provided for such purpose. The lower end of the upright 22 is pin connected to a suitable base member 24 at 25 associated with a portion of the pit 10 such as the shelf 26 thereof, as clearly shown in Fig. 3.

Two of these base members 24 are provided, one on each side of the vat 12 and each base has two uprights 22 extending from the ends thereof so that the four ends of the two I-beams of the supporting framework 15 are adapted to rest. within the socketed ends of the four articulated uprights. Intermediate their length, the uprights are suitably interconnected as shown in Figs. 6 and 7 by a con necting rod 27 thereby maintaining said uprights in fixed relationship to each other and maintaining them always in such relationship that when they move they maintain their parallelism. As clearly shown in Figs. 1 and 2, connecting rods 28 are provided-between the last uprights and a crank shaft 29 to which they are so connected that upon the actuation of the crank shaft by means of the prime-moveror source of power 30, which may be an electric motor, acting through friction clutches 31 and the reducing gears 32, causes said connecting rods to move eccentrically, causing, in turn, the uprights 22 to pivot at their pin connection 25 with the base members 24 and to describe the are subtended by the angle a, the movement constituting that limited by the aforesaid angle. The crank shaft 29 is suitably supported in bearings 33 supported by a shelf 34 of the pit,

as shown in Figs. 1 and 2.

When the aforesaid movement is imparted to the uprights 22 by'meansof the connections therewith of connecting rods 28, the rollers 21 of supporting framework 15 move within said sockets 23 so as to provide a nonrigid or yielding connection, that is, one which will not interfere with the movements above described. The supporting framework is, however, given a limited movement in this manner which is imparted to the ma terial supporting tray 13 so as to cause the same to move back and forth in the pickling fluid in vat 12, thus causing the pickling fluid to be surged back and forth vigorously and through or about the material, thus completely reaching the entire inner and outer surfaces of the material and completing the pickling action in a minimum time due to the constant agitation of the pickling fluid and the resultant reaching of the surfaces of the material by new unexpended fluid.

The supporting framework 15 is suitably interconnected by theframework35 and is provided with an apertured extension 36 so that a crane or other lifting device, not shown, may be readily utilized tolift-the tray full of material out of the pickling fluid so that it may be unloaded and a new supply substituted, the roller and socket connection between the upper end of the articulated upright, and the ends of the supporting framework being readily disengageable so that no connections prevent the simple lifting off of the supporting framework with its attached tray, with or without the material thereon.

Coming now to Figures 8 to 12, inclusive, I provide a source of power 10 which actuates a crank shaft 11' to whichare eccentrically connected at each end thereof a pair of connecting rods 12 suitably connected to movable elements 13" associatedwith a sup porting framework 14, from which depends a pipe or other material supporting tray 15, thereby enabling the latter to be suitably moved in a pickling fluid for the purposes of eiiiciently and completely pickling the material contained on said tray. I provide a pit 16 of suitable type andconstruction and supported therein as by supporting blocks 17 is the vat 18 of any suitable'or desired construction and adapted to contain a pickling fluid, which latter may be any of the usual fluids generally utilized for such purposes and well known in the industry. Y

Suspended in said vat is the material supporting tray 15 provided. with upstanding partition members 19 for the usual purposes, the tray being connected by means of rods 20, for example, to the supporting framework 14' composed of a suitable Lbeam construction and provided with the'portion 21' so that the supporting framework and tray may be all lifted or otherwise transported by a suitable crane or other lifting device, not shown, as more fully explained above anent Figures 1 to 7 inclusive. V

The supporting framework 14 is constructed as shown in Fig. 8 and, as stated, includes two transverse I-beams the ends of and the reduction gearing 32 power isturned on, the

reeware which rest. in socket -me'1nbers 22 suitably connected with the movable, elements 13 whichmay terminatein sleeves 24! in which are rotatably mounted in the case where a rotatable member is used, the shaftsof roll- ,er's 25" These rollers are adapted it operate ingu deways 26 in framework 27, supported onsupports 27 on shelf 27 of pit 16, all

arranged as shown in Figs. 10 and 11, the guideways or slots 26 being horizontal, and

bothguiding and limiting the movement of the rollers-25 and hence the movement of the material supporting tray 15. i V

The sleeves 24 in which the shafts of rollers'25 operate have projections 28 in which are pin co-nnected the connecting rods 29', onesleeve haidng a similar formation 30 diametrically opposite, to which is also pin- }connected the connecting rod 12 ecce'ntricall y connectechas shown in Fig. 11, with the 's-haf-tl1 which-is supportedin bearings El and actuated through the source of power 10- v and friction clutches 33. y f a i It will thus .be seen that whenthe source of rollers will be caused to roll back and forth in slots 26 in framework 27 through the actuation of connecting rod112' and a suitable movement will, therefore, begiven tothe material supporting'tray 15 and hence pic {ling fluid will be surged vigorously back and forth through and over the material thus thoroughly and'completely pickling the same in the cienc r I hllve discovered further that if the rollers are caused to describe a curvilinear or arcuate path instead of a straight line path in a horizontal direction, even greater eilic ency will be obtained and the'additional stirring up of the pickling fluid will enhance the effeet by even further diminishing the time and increasing the action. This curvilinear or arcuate movement can readily be obtained by configuring the slots 26 or framework 27' in the form shown in Fig. 12, wherein the slots 26" are curved, thus imparting a corresponding motion to the pipe supportingtray.

It is not necessary that rollers be provided as I find that satisfactory efficiency, can be as readily obtained with any suitable sliding members which need not roll and hence which need not be so mounted as to enable them to roll. In this connection, reference is had to Fig. 12a, wherein is shown guide ways 27a provided with slots 26c which are straight-line slots. Slidable blocks or other suitable members 25a operate in slots 26a by sliding back and forth therein as will be understandable from the foregoing. If necessary or desirable, these sliding members may be lubricated suitably and composedof any preferred material. In this way, 1 provide a substantially equally satisfactory minimum time with the maximum of eiiimeans for moving-thematerialsupporting' pairs. .If found desirable or necessary the guideways maybe slightly greased to enable the sliding meniber t'o pass back and forth readily-without generating too much fric' tion or too much heat: andrhence-without puttingtoo much ofaload upon the sourceof power and its connections, although the source of power and connections are, of course, designed to take care of loads :suwstantially in excess of what they are likely to be required to withstand.

It is"unders-tood that'the above is more illustrative than limitati-ve and that. I may vary'the connections and details to'suit the particular requirements" of any batch of material and that any such changes, sub= stitution, additions or omissions fall within the spirit and'scope' ofmy in 'ention.
